FASTENING. a

SPECIFICATION forming part of Letters Patent No. 593,721, dated November 16, 1897.

Application filed March 9, 1897.

To all whom it may concern:

Be it known that I, CHARLES VICTOR HOFF- MAN, a citizen of the United States, residing at Sidney, in the county of Hunterdon and State of New Jersey, have invented certain new and useful Improvements in Rubber-Shoe Lacings, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to rubber shoes and to means for lacing or fastening the same; and the object'thereof is to provide improved fastening devices for shoes of this class which are formed integrally with the material of the shoe.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, inwhich- Figure. 1 is a perspective View of an overshoe provided with my improvement; Fig. 2, a front View of a portion thereof, on an enlarged scale, and showing the separate parts of the shoe connected; Fig. 3, a similar view showing the parts disconnected; Fig. 4., a section on the line 4 4' of Fig. 2, and Fig. 5 a section on the line 5 5 of Fig. 3.

In the drawings forming part of this specication the separate parts of my improvement are designated by the same numerals of reference in each of the Views, and in said drawings I have shown at 7 in Fig. 1 an ordinary rubber overshoe, in the front of which is formed the usual opening 8, and the separate parts of the front of the shoe are designated in the other figures of the drawings by the reference-numerals 9 and 10.

In the practice of my invention I provide means for securing the separate parts 9 and 10 of the shoe together,which consist of semicircular heads 11,which are formed on or connected with the opposite sides 9' and 10 by means of necks 12, between each of which is asemicircular space 13, and the semicircular heads 11 are thicker than the material of the sides 9 and 10 of the shoe, and the semicircular spaces '13 are much smaller than the semicircular heads 11, and in practice these semicir- Serial No. 626,565. (No model.)

cular heads 11 are interlocked in order to connect the separate sides 9 and 10 of the shoe, and when thus connected the appearance thereof is clearly shown in Fig. 2.

In the operation of connecting the separate sides 9 and 10, as above described, the necks 12, by which the semicircular heads 11 are connected with the opposite sides, pass through the semicircular spaces 13, and in the construction shown one of the semicircular heads 11 on one side and at the top thereof is cut in half, While the bottom semicircular head on the opposite side is similarly formed, these particular heads being formed in the shape of a quadrant; but'this feature of the construction is immaterial and may or may not be employed.

My improved fastening device is simple in construction and operation and my in vention is not limited to the application thereof to rubber shoes, and it will be apparent that the heads 11 may be of different form, if desired,

and other changes in and modifications of the construction herein described may be made without departing from the spirit of my invention or sacrificing itsadvantages.

' Having fully described my invention, I claim as new and desire to secure by Letters Patent The herein-described rubber-shoe lacing consisting of semicircular heads 11, secured to the flaps of the shoe by means of necks 12 between each of which is formed a semicircular space 13, and the said heads 11 being thicker than the material of the sides of the shoe whereby shoulders are formed on the said heads adjacent to the necks 11, and the semicircular space 13 being smaller than the said semicircular heads, substantially as and for the purpose described.

In testimony that I claim the foregoing as my invent-ion I have signed my name, in presence of the subscribing witnesses, this 8th day of March, 1897.

CHARLES VICTOR HOFFMAN.
